14. How can I have my water tested?
Services for water testing are available from private laboratories for a fee. This fee varies greatly depending on the number of constituents you would like tested for in the water. The Chicago Water Department, Water Quality Bureau, Water Purification Laboratories, performs quarterly chemical analysis on the water they supply to the Commission. The Commission sends water samples to the Illinois Environmental Protection Agency Laboratories monthly for bacterial testing. The Commission's water meets all State and Federal drinking water standards. To obtain a booklet of qualified laboratories call the Illinois Environmental Protection Agency, Division of Laboratories, at 217-782-6455.
